A UNITED STATES" PATENT OFFIC PERCY H. RUSSELL, OF SANGERVILLE, MAINE, ASSIGNOR OF ONE-HALF TO 7 JAMES L. GORDON, OF SAME PLACE.

-ALARM APPARATUS FOR CARDlNG-ENGINES.

SFEGIFICATION forming part of Letters Patent N 0. 628,493, dated July 11 1899;

Application filed March 1 8, 1 89 8.

To all whom it may concern:

Be it known that I, PERCY H. RUSSELL, a

citizen of the United States, residing at Sangerville, in the county of Piscataquis and State of Maine, have invented certain new and useful Improvements in Alarm Apparatus for Woolen Oarding-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it appertains to make and use the same, ref- I drawings, whereby the object is accomplished with greater efiiciency than has heretofore been secured.

In the accompanying drawings similar 1etters represent the same parts of the invention.

Figure 1 is a perspective view of that portion of a carding-engine from which the work is delivered, showing my invention as applied to the ordinaryworking parts of such a machine and acting in combination with them. Fig. 2 represents a full face view of the same. Fig. 3 represents the parts of my invention separate from the other portions of a carding-machine, the position of the parts being normal or in readiness for an alarm should a break occur. Fig. 4 represents the same in position of giving an alarmafter a break in the work.

In Fig. 1, a a represent the draw-rolls'as usually arranged on carding-engines to re-, ceive the product from the dofifer and deliver itfrom the machine. his the sliver or drawing carried upward from the draw-rolls as fast as delivered to be fed into another machine in the usual process of manufacture. c c are toothed gear-wheels which revolve the Serial No. 674,853. (No model.)

draw-rolls a a. d and e are toothed gears conveying power to the wheels 0 c. f is a driving-pulley taking power from above by means of the beltg g and by means of which the gears c, c, d, and e are operated. h h h is the frame in which the draw-rolls a a are journaled, all as usually arranged in cardingengines.

A is a horizontal shaft or rod journaled in the bearings or supports 0 O, which are attached to the bottom of the draw-roll frame hh. A is an arm attached to the shaft A, at right angles thereto,outside the support 0, and A is an arm, called the feeler-Wire,attached to A'at its outer end and turnedinward parallel to the shaft A. A is an arm attached to the opposite end of the shaft A, outside the support 0, at right angles with A, but as compared with A in a direction forming an obtuse angle.

"A is a hook or turned end at the outer ex tremity of the arm A B is a continuation of the shaft carrying the driving-pulley-f and the toothed gear 6, the same beingjournaled at K in the support 1.

(J is a collar upon the shaft B, held fast by means of a set-screw and having an arm, as shown by the dotted lines, and D is an alarmbell or gong-cup attached to said arm 0.

E is a spring attached to the arm or col- 8:) lar G, holding a hammer near to the bell D, and having a projecting finger Fnear said hammer.

The parts A,'A, A A and A although so far described as separate pieces attached to each other are really as constructed one piece, the rod being bent so as to form the whole. The lower portion A and A is of such weight that when the upper portion A and A are not held upright it will cause the, 0

portion A to turn automatically in its bearings, the upper arm A A falling outward and the lower' arm A and A downward toward the shaft B.

The alarm-bell or gong-cup D, collared to the shaft 13, revolves around it as the shaft turns. Its position on the shaft is so arranged with regard to the arm A and the curve or hook A that when the hooked end drops by gravitation the hook A -catches the finger F I00 of the spring and hammer E, drawing it back, and then releases it, when the spring throws the hammer against the gong-cup D, repeating this catching, releasing, and striking with every revolution of the shaft as long as the arm A and A remains down.

In operation the arm A A is held up away from contact with the finger F by passing the sliver or drawing 1) in front of the feeler-wire A So long as the sliver or drawing is continuous or unbroken the arm A A is held upright. Wheneveritbreaks,thefeeler-wire is released, falls forward,-and the arm A A falls into contact with the alarm, as shown by the dotted lines 70 70, Fig. 1.

The alarm as described is attached to woolen carding-engines at the point where the work called the sliver or drawing is delivered from the machine through the draw-rolls for the reason that a break in the work rarely ever occurs at any other place in its passage to the feeding-table of another machine. By thus early sounding an alarm the defect is discovered and easily mended long before the broken end reaches and disarranges the feeding apparatus of thenext machine.

Having thus fully described my invention and its working, what I claim, and desire to secure by Letters Patent, is-

A pivoted rod attached to a carding-engine near the draw-rolls, having an arm carrying a feeler-wire adapted to normally be upheld by the sliver when the drawing is unbroken, and a second arm carrying a hook at its extremity, adapted to drop downward by gravity whenever the feeler-wire is released by a break in the drawing, all in combination with a revolving shaft carrying an alarm-bell adapted to be sounded by contact with said hook at each revolution when the same has dropped downward; all as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

PERCY H. RUSSELL.
